Management of pressures under high groundwater with hydroshields
Working at more than 5 bar of groundwater pressure requires the use of a closed shield of the hydroshield type.
Closed shield tunnel boring machines
Tunnel construction: Hydroshield and EPB
En EUROHINCA destacamos en la construcción de túneles utilizando tuneladoras de escudo cerrado, conocidas como Hydroshield y EPB (Earth Pressure Balance). Estas máquinas se adaptan perfectamente a terrenos blandos, suelos inestables o con alta presencia de agua.
Contamos con experiencia internacional en obras subterráneas, como túneles de alcantarillado urbano y drainage works, donde estas técnicas han demostrado su eficiencia.
Subway tunnels with closed shield tunnel boring machines (TBMs)
Gracias a su capacidad de controlar la presión en el frente de excavación, las tuneladoras de escudo cerrado son ideales para entornos urbanos, zonas costeras o suelos inestables. La EPB utiliza el propio material excavado como apoyo, mientras que el hidroescudo emplea una suspensión de bentonita para garantizar estabilidad.
Puedes consultar más especificaciones técnicas en las guías de túneles de la ITA.

Frequently asked questions on closed shield TBMs
Respondemos las dudas más comunes sobre la aplicación de escudo cerrado en distintos tipos de obras subterráneas.
What are closed shield TBMs?
Closed shield tunnel boring machines are machines used in tunnel excavation. These tunnel boring machines, such as the Hydroshield and EPB, are designed to stabilize the ground and handle different ground conditions, providing safety and efficiency during subway construction.
What is the difference between Hydroshield and EPB?
Hydroshield TBMs are ideal for soils with high water pressure, providing a shield against seepage. EPB (Earth Pressure Balancing) TBMs are suitable for mixed and soft soils, balancing soil pressure and avoiding collapse.
In which projects are closed shield TBMs used?
Closed shield TBMs are used in a variety of subway projects, including submarine outfalls, vertical shafts, and segmental tunnels. They are essential in the construction of subway infrastructure in urban and rural areas.
What are the advantages of using closed shield TBMs?
Advantages include safe and efficient excavation, the ability to handle different soil types, and minimized ground disruption. These TBMs ensure tunnel stability and environmental protection during construction.
How does Eurohinca ensure the quality of its projects?
Eurohinca has more than 20 years of experience and has completed more than 240 projects internationally. It uses advanced technology and specialized equipment, ensuring the precise and efficient execution of tunnels, with a focus on safety and quality.
Is it possible to use these tunnel boring machines in urban projects?
Yes, closed shield TBMs are ideal for urban projects because of their ability to excavate in a controlled and safe manner in densely populated areas, minimizing surface disruption and impact.
